Since dogs are only supposed to be washed every few months, does that mean wolves, dogs, and foxes also don't take showers/baths? Would shower/baths not be a thing?.... would they just.. lick themselves? (And of course brush)

How would diets work, like I can understand most normally herbivorous species remaining as such but what about omnivores and carnivores?? Do non sapient versions of the species exist and get used as a food source or is everyone just vegetarian now??

Also how would things like clothes work, would there be universal sizes and designs for each type (such as a universal mammal size etc) or would everything need to be tailor made to fit each distinct person....man tailors would make bank if thats the case lol

How can deer and other horned species wear hats? Like, do they have to gets custom hats made?

My guess would be the material would be different. I have a cervitaur that wears a hat made of stretchy fabric. Ether that or there's clips under the hats that they could adjust to size to make the holes bigger.
